#### HARD CALCULUS QUESTION, HEEELP!!!

If f is integrable on [a, b], show by example that : tF (t) = ∫ f(x) dx ais continuous but need not to be differentiable.note: the integral from (a) to (t).

#### what's the answer to this question: Let

x^2f(x) = ∫ e^(-t^2) dtxfind the critical points of f(x).note: integral from (x) to (x^2).
